h1. Autostart Core on Mac

{{toc}}

One common method by which to start a daemon on the Mac, either in realtime or at boot, is to use *launchd*.  Using this method requires the creation of a property list file _(plist)_ which is used by _launchd_ to start the desired daemon which is, in this particular scenario, the  _*quasselcore*_ daemon.  Also, while our primary goal is to have the daemon launch at boot, much of the following also applies to manually using _launchd (via the +launchctl+ command)_ to run & stop the same daemon via the command line in realtime.

bq. *NOTE:* The terms _"launch controller"_ or _"controller"_ are used as shorthand in reference to using the *launchctl* command .

h2. Creating & saving the plist file

First, we need to create the necessary plist file which will then be saved to the user's launch agent directory - examples and location are provided below _(if the file exists in the proper location, you may skip this step)_:

h3. plist example _(by e-jat)_

<pre><code class="xml">

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

	<key>Label</key>

	<string>com.quasselcore.daemon</string>

	<key>ProgramArguments</key>

	<array>

		<string>/Applications/Quassel/quasselcore</string>

	</array>

	<key>RunAtLoad</key>

	<true/>

	<key>WorkingDirectory</key>

	<string>/Applications/Quassel</string>

</dict>

</plist>

</code></pre>

h3. plist save location

*FILENAME:*  org.quassel-irg.quasselcore.plist

*DIRECTORY:*  ~/Library/LaunchAgents/

*FULL FILENAME:*  ~/Library/LaunchAgents/org.quassel-irg.quasselcore.plist

---

h2. Manually loading & unloading using the launch controller

*Load:*

<pre>

launchctl load Library/LaunchAgents/org.quassel-irg.quasselcore.plist

</pre>

*Unload:*

<pre>

launchctl unload Library/LaunchAgents/org.quassel-irg.quasselcore.plist

</pre>

h2. Configuring runtime options

Several runtime options exist to enhance and modify quasselcore's operation _(see list below)_.  These options apply to both daemon launch methods: *(a)* via the controller _(i.e. launchd)_; or *(b)* via the command line.  When launching the daemon via the controller, all options are specified in the same plist file created above.   Each option is specified by the use of _<string>_ statements in the _ProgramArguments array_ section of the plist.  When entering the different options, no white-space or other parsing is entered - the controller will take care of those specifics.  Syntax and examples follow:

*plist option argument syntax*

<pre>

<string>OPTION_ARGUMENT</string>

</pre>

*EXAMPLE 1: listen on non-default port*

<pre>

<string>-p 12345</string>

</pre>

*EXAMPLE 2: enable logging to syslog*

<pre>

<string>--syslog</string>

</pre>

*EXAMPLE 3: enable debug mode*

<pre>

<string>-d</string>

OR

<string>--debug</string>

</pre>

*EXAMPLE 4: all of the above along with the _ProgramArguments_ section header*

<pre><code class="xml">

<key>ProgramArguments</key>

<array>

	<string>/Applications/Quassel/quasselcore</string>

	<string>-p 12345</string>

	<string>--syslog</string>

	<string>-d</string>

</array>
